Ocean Acidification

Problem Scenario

It is important to know how the amount of acids are in the ocean because the ocean animals will be affected by amounts of acids in the water.

Broad Question

Does Acidification effect the animals in the ocean water?

Specific Question

Does shells dissolve in different amounts of acid?

Hypothesis

The more acid (lemon) in the water the more it will effect the shell.

Variables

Independent Variable:

The different types of acids

Dependent Variable:

the amount of change.

Variables That Need To Be Controlled:

water and time

Vocabulary List That Needs Explanation

Acidification - the process of becoming acid or being converted into an acid.

General Plan

I will take shells mass and mark them and put them in different amounts of acids and soke them for four day and mass them again and see how they changed over time and did it lose weight over the five day.

None

Safety Or Environmental Concerns

None

Detailed Procedure

1. I mark the shells with nail polish
2. Mass the shells
3. The put lemon juice of different amounts
4. Take data in four days
5. Take them out of the cups
6. Mass again after
7. Compare data

Results

During this experiment I have questioned and tested if shells dissolved with different amounts of lemon juices. The sells dissolved with the water has more acid or lemon juice. The more the more the lemon juice the more the shells will devolve, the one cup of lemon has dissolved the most with a one hundred percent gone. The half cup got less dissolving than the full cup but more than the one forth of a cup of lemon juice that had the most little change in the weight.

Conclusion

I have stated in my hypothesis that the more acid (lemon Juice) the more the shell will be effected. So, I will accept the my hypothesis. I accepted the hypothesis because the more lemon juice I put in the cup the more the shell had dissolved over the time of five day's. Each time I did it it was the same. My data had stated that the shells have dissolved fully with the cup of water filled with one cup of lemon juice. Also I have tried to see if my hypothesis was true by having the same experiment with only half a cup of lemon juice and repeated with only a forth a cup of lemon juice and all of this experiments pointed to my hypothesis was true.

Discussion

This project on ocean Acidification was accepted by my hypothesis. Some patterns I have notice in my experiment is the more lemon juice in the water the more the shell dissolve. Everything my experiments showed at lest 41% weight loss. The relationship between my to variables are strong because the my independent relievers to my dependent variable. This is because if their was no independent variable the is no dependent variable. My independent variable for this question is the amount of lemon juice and the dependent variable is percentage for change. I was able to find the answer for my question with is 'does shells dissolve in different amounts of acid'. The answer is that it was true and so then I can determinate if the different amounts of acid will effect the animal's of the ocean.

I believe that my experiment went perfectly fine by me personalty I could have improved this experiment very little. the why I could have changed this experiment by having more and less acid in the water and did more experiment and also I think that I should have made it longer experiment, other wise this experiment went by perfectly. my data was also perfect. I have and did the math wise to make the data perfect and all correct. If my data was wrong then I would have to start over to make this page perfect.

Benefit to community and /or science

I believe that my question could effect the community and science. I think this because all off pollution that we are causing can be stopped in a small community and we can do thing by riding or walking to school or work on the day of the month for everyone. Ocean Acidification can very severe and can hurt the animals of the sea. Acidic water dissolves the shells and skeletons of clams, corals and many of the tiny creatures at the base of the ocean food chain like plankton, thereby affecting the entire whole ocean.

Abstract

My question is for this project is does shells dissolve in different amounts of acid(lemon juice). This experiment looks at if lemon juice does effect the animals in the sea in different amounts of lemon juice like one forth of a cup a half of a cup and a whole cup of water and lemon juice and I have asked this question because I love to care for animals and also I love the ocean. This project can help people care for the oceans and the the animals in it and that is another reason I did this project. My hypothesis was that the more acid in the water the more the shells will dissolve. So, I will except my hypothesis and this will or can change to world.
